Air Bag Deactivation Procedures Audi A6 C4

SPECIAL CARE DURING MECHANICAL REPAIRS

Note. References to SRS and SIR by manufacturers refer to Supplemental Restraint Systems (SRS) and Supplemental Inflatable Restraints (SIR).

Observe manufacturer service precautions when working on a vehicle equipped with an air bag system. See appropriate manufacturers SERVICE PRECAUTIONS.

Electrical sources should never be allowed near inflator on back of air bag module. Never probe air bag system electrical wires with analog volt-ohmmeter or test light. Always disable air bag system before servicing vehicle. See appropriate DISABLING & ACTIVATING AIR BAG SYSTEM procedure. Failure to do so could result in accidental air bag deployment and possible personal injury.

If air bag system is not fully functional for any reason, DO NOT drive vehicle until system is repaired and is again operational. DO NOT remove bulbs, modules, sensors or other components, or in any way disable system from operating normally. If air bag system is not functional, park vehicle until system is repaired and functions properly.

SYSTEM OPERATION CHECK

When ignition is turned on, SRS indicator light should come on for about 6 seconds and then go off. While vehicle is driven, light should not come on or flash. If SRS indicator light does not operate as specified, system must be inspected/repaired as soon as possible.

SERVICE PRECAUTIONS

Observe these precautions when working with air bag systems and seat belt pretensioners (if equipped)

1. Disable SRS before servicing any SRS or steering column component. Failure to do this could result in accidental air bag deployment, possibly causing personal injury. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/audi/a6/c4-1994-1997/remont/restraints/#air-bag-deactivation-procedures__disabling-activating-air-bag-system) .
2. Wait about 3 minutes after disabling air bag system. A back-up power circuit capacitor (in SRS control unit) maintains system voltage for about 3 minutes after battery is disconnected. Servicing air bag system or seat belt pretensioners before 3 minutes may cause accidental deployment and possible personal injury.
3. After an accident, all SRS components, including wiring harness and brackets, must be inspected. If any components are damaged or bent, they must be replaced, even if air bag did not deploy. Check steering column, knee bolster, instrument panel steering column reinforcement plate and lower brace for damage. DO NOT service/repair any component or wiring. If components or wiring are damaged or defective, replacement is required.
4. Always wear safety glasses when servicing SRS or handling an air bag or seat belt pretensioner (if equipped).
5. DO NOT attempt to disassemble air bag assembly or seat belt pretensioner (if equipped). Neither component has any serviceable or reusable parts.
6. A replacement air bag assembly must be stored in its original special container until used for service. Special container must be stored in a clean, dry place, away from sources of extreme heat, sparks and high electrical energy.
7. When placing a live air bag assembly on a bench or other surface, always face air bag and trim cover up, away from surface. This will reduce motion of air bag assembly if accidentally deployed.
8. After deployment, air bag assembly is very hot. Wait 30 minutes before handling.
9. After deployment, air bag surface may contain deposits of sodium azide and potassium nitrate, which can irritate skin. Always wear safety glasses, rubber gloves and long-sleeved shirt during clean-up, and wash hands using mild soap and water. Follow correct disposal procedures.
10. DO NOT allow any electrical source near inflator on back of air bag assembly or near 3-pin connector of seat belt pretensioner.
11. When carrying a live air bag assembly, trim cover pad should be pointed away from your body to minimize injury in case of accidental air bag deployment.
12. DO NOT probe any wire through insulator; this will damage wire and eventually cause failure due to corrosion.
13. When performing electrical tests, always use test harnesses recommended by manufacturer. DO NOT connect tester probes directly to component connector pins or wires.
14. DO NOT use any type of electrical equipment other than that specified by manufacturer.
15. If SRS is not fully functional for any reason, vehicle should not be driven until system is repaired. DO NOT remove any component or in any way disable system from operating normally. If SRS is not functional, park vehicle until repairs can be made.

9. DO NOT expose front air bag sensors, center air bag sensor or steering wheel pad directly to heat or flame.
10. Information labels are attached to air bag components. Follow all notices on labels.
11. After work on SRS is completed, check air bag warning light to ensure system is functioning properly. See «SYSTEM OPERATION CHECK»(/audi/a6/c4-1994-1997/remont/restraints/#air-bag-deactivation-procedures) .
12. Always wear safety glasses when servicing or handling an air bag.
13. When placing a live air bag on a bench or other surface, always face air bag and trim cover upward, away from surface. This will reduce motion of module if it is accidentally deployed.
14. After deployment, air bag surface may contain deposits of sodium hydroxide, which irritates skin. Always wear safety glasses, rubber gloves and long-sleeved shirt during clean-up. After clean-up, wash hands using mild soap and water.
15. Carry a live air bag module with trim cover (air bag) pointed away from your body to minimize injury in case of accidental deployment.
16. If SRS is not fully functional for any reason, vehicle should not be driven until system is repaired and again becomes operational. DO NOT remove bulbs, modules, sensors or other components or in any way disable system from operating normally. If SRS is not functional, park vehicle until it is repaired and functions properly.

Turn ignition switch to LOCK position. Disconnect and shield negative battery cable. Wait at least 90 seconds before working on system. Remove steering wheel pad (air bag). On vehicles equipped with passenger-side air bag, disconnect passenger-side air bag connector, accessible through finish plate in glove box.

Reconnect passenger-side air bag connector (if equipped). Install steering wheel pad. Reconnect negative battery cable. Perform SYSTEM OPERATION CHECK .

An air bag light is located on left side of instrument cluster. Air bag, light is used to indicate readiness of system. This light, which glows when ignition switch is on or engine is started, will stay on approximately 3 seconds while air bag control unit performs an electronic test cycle of system.

If air bag light does not glow when ignition is on or does not go out after 3 seconds, a fault probably exists in system. If a fault occurs while ignition is on, it is stored in fault memory. Warning light will then glow and air bag system will be switched off. If warning light glows or flickers while driving, air bag system should be tested. Repair as necessary.

Observe these precautions when working with air bag systems

1. Before disconnect battery cable(s) and disabling air bag system, obtain radio security code from vehicle owner.
2. DO NOT use computer memory saver tool. Using computer memory saver tool will keep air bag system active and may cause accidental deployment of air bag unit.
3. Disable air bag system before servicing any air bag system or steering column component. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/audi/a6/c4-1994-1997/remont/restraints/#air-bag-deactivation-procedures) .
4. Because of critical operating requirements of system, DO NOT attempt to service any air bag system component.
5. Air bag parts should not be left unattended. They should be installed in vehicle immediately after obtaining them.
6. Air bag components which have been dropped more than 20 inches should not be used.
7. Chemical cleaners, oil and grease should not contact vinyl covering on air bag unit.
8. DO NOT place stickers or covers on steering wheel.
9. Always disable air bag system before performing electric welding on vehicle.

To disable air bag system, disconnect and shield negative battery cable. To activate system, reconnect negative battery cable. Perform a system operational check to ensure proper system operation. See SYSTEM OPERATION CHECK .

Turn ignition switch to ON position (engine not running). If no fault codes are present, SRS warning light will go out after 10 seconds. If SRS is malfunctioning, SRS fault code will be stored in crash sensor memory during the following conditions

1. SRS warning light does not glow.
2. SRS warning light does not go out after 10 seconds.
3. SRS warning light does not go out after engine is started.
4. SRS warning light comes on while driving.

If SRS warning light indicates a malfunction, diagnose and repair as necessary.

Seat Belt Tensioner Inspection

1. There are 2 methods of determining seat belt tensioner activation. Start by pulling seat belt out and releasing it. If belt normally extends easily to full length, tensioner has not been activated. If either belt sticks, jerks when reeling and unreeling or fails to reel, both belts must be replaced.
2. If seat belt tensioner activation can not be determined, turn ignition switch to OFF position. Disconnect negative battery cable. Remove "B" post inner panel. Insert a steel rod into tensioner tube to establish position of plunger.
3. On 850 models, if plunger position is near bottom of tensioner tube, seat belt tensioner has been activated and both belts must be replaced. If plunger position is near top of tensioner tube, seat belt tensioner has not deployed.
4. On 960 models, if plunger position is near, bottom of tensioner tube, seat belt tensioner has not deployed. If plunger position is near top of tensioner tube, seat belt tensioner has been activated and both belts must be replaced.

Observe these precautions when working with air bag systems

1. Always disable SRS before performing any air bag repairs. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/audi/a6/c4-1994-1997/remont/restraints/#air-bag-deactivation-procedures) .
2. Before disconnect battery cable(s) and disabling air bag system, obtain radio security code from vehicle owner.
3. Always ensure radio is off before disconnecting battery. This will prevent damage to radio microprocessor.
4. Always wear safety glasses and gloves when handling a deployed air bag module and/or seat belt tensioners. Air bag module and/or seat belt tensioners may contain sodium hydroxide deposits, which irritate skin.
5. Use caution when handling sensors. Never strike or jar sensors. All sensors and mounting bracket bolts must be tightened carefully to ensure proper sensor operation.
6. Never apply power to SRS if any SRS crash sensor is not securely mounted to vehicle.
7. Never make any measurement directly on air bag module(s) or seat belt tensioners.
8. Wiring repairs should not be performed on any portion of SRS wiring harness.
9. Always handle air bag modules with trim cover away from your body. Always place air bag module on workbench with trim cover facing up, away from loose objects.

Scheme 29

1. Before proceeding, see «SERVICE PRECAUTIONS»(/audi/a6/c4-1994-1997/remont/restraints/#air-bag-deactivation-procedures). Before performing any repairs, turn ignition switch to OFF position. Disconnect and shield negative battery cable. Locate and disconnect air bag module and seat belt tensioner connectors and passenger-side air bag module connector.
2. On 1995-96 850 and 1996 960 models with side air bags, remove cover from side seat compartment. Remove transport safety device from inside of cover. Install transport safety device onto side impact sensor. (Scheme 29) Repeat procedure for opposite front seat. SRS system is now disabled.

After repairs are performed, ensure all wiring and component connectors are connected. Turn ignition switch to ON position. Connect negative battery cable. Ensure vehicle is not occupied when connecting battery cable. Ensure system is functioning.
